I have not seen it either and I have only received 2 updates so I am still eligible. I checked myself last week thinking the same as you, that the update was late.

I live in an area of Northern Virginia where new roads, some of them significant, are being built, extended, and/or connected all the time. I think I have installed two official map updates from Audi and I am still waiting for some of these new additions to be included. Its not a huge deal, but some of the time my B9 is "lost in space" while I'm on these new roads not in the Nav.

I solved the problem by using the already installed Apple CarPlay and the Waze app. For me it's a vastly superior Nav system which includes all the roads no matter how new they are, plus audible realtime police and road hazard warnings as well as current traffic conditions. You can adjust it to give you an audible beep if you exceed the posted speed by a preset amount and a host of other personalized features. Honestly, since I have started using it, I have never gone back to the standard Audi installed maps.

Yes, you can view the Waze map on the main center screen and it’s contollable using the main round center console ****. It adjusts in size according to the cars’s speed and it orientatable north which is as I personally prefer. You can make a lot of selections on what you want to see or not see on the Waze app on the iPhone, then once you plug the phone in with the connection cable it takes the map with your settings and puts it on screen once you select Waze from the CarPlay main control screen.

I changed my phone data plan to an unlimited everything plan when I started using CarPlay. It’s functioned very well for me and the music streaming capabilities are great. I mainly use Pandora, although there are several other apps available, and have a number of different music genre channels set up on the app. They all come up on the center screen and you can change and make selections using the control ****. The music quality is great and IMO makes Sirius radio obsolete.

As to WiFi, I use my phones private hotspot. I haven’t had the need to use it all that much so far, but it seems to work well and has reasonable speed.

Yes, iOS 12 on iPhones allow third party maps apps to support CarPlay, which means you can “project” Waze and google maps on to the A4 display.
